    Hello Ira, I've yet to get to this exciting stage but I'm just wondering if you have calibrated all the sensors and their respective monitors by putting all the sensors in a pot of cold water and then bringing it all to boiling point to ascertain any discrepancies which might exist in these items alone ?

    I have just received my Filser TRT 800 mode S transponder and am pondering on where to position the antenna. Has anyone already successfully fitted, tested one.Also has it been approved? Ken.

    Interesting data! On my bird there are ring probes under the spark plugs, and one Rotax cht probe is in use. The ring probe on #3 indicates about 15 C higher as the Rotax probe. Since oil- and coolant temperature are coupled in the oi-water heat exchanger, i am using the oil temperature as coolant temperature indication. All the temperatures are within 1 degree when the engine is cold. If the engine pre-heater is on and the cowl under it's blanket, all temperatures are again within 1 degree of about 50 C. My concern is in flight, especially on low power, like 55%, the front ring terminals are around 60 C, and the hottest rear is around 100, with 95 C for the other. Oil will typically be 85 to 90 C That's with an OAT of -5 to -10 C. My next move is to temporarily block the standard air cooling openings and see if the Rotax shroud and it's intake will produce a more even picture. And then hope for acceptable results in the hot summer. Regards, Jos Okhuijsen Visit - www.EuropaOwners.org

    Ira Are you not monitoring the VDO probes with your EFIS because they are ungrounded probes? I am hoping that changing the VDO probes to Westach grounded alternatives (which fit the holes in the head) will work. They certainly read on the EFIS but we haven't had the engine running yet. regards Paul On 9 Apr 2008, at 13:49, rampil wrote: > > I finally completed my cylinder head temp monitoring system so now > I have 3 sites of measurement: Regular Rotax VDO probes into > the heads of Cylinders 2, 3 going to an analog gauge; > Ring-type CHTs installed under the Rotax CHT probes and monitored by > my Blue Mountain EFIS, and finally the Lockwood/Rotax coolant temp > probe with a Blue Mountain probe going into the EFIS. > > So far, I have only done cowl-off, static testing but the results are > interesting: > The coolant temp at 4000 rpm is 20F higher than the Rotax/VDO > which is about 20F higher than the ring probes outside the block. > > These will probably change when cowled and at cruise and climb which > I plan to test when I return from SnF. > > -------- > Ira N224XS > > > Read this topic online here: > > http://forums.matronics.com/viewtopic.php?p=175679#175679 > >

    I stuck a Bob Archer thing against the luggage bay bulkhead. First wrong way, it has to be horizontal. The radio stays clean, no ticking sounds from the transponder, and ATC sees me even in the steel hangar :-) It's a nice transponder. and backs up as an altimeter with it's encoder built in. I am very happy with it. Regards, Jos Okhuijsen Visit - www.EuropaOwners.org

    Hi Kingsley, Be a former quant, yes, I love calibration! In situ the probes all read equal when the engine is cold. Hi Jos, It would be very interesting to compare the ring location I have vs the spark plug site. I was advised by Kerry at Lockwood not to go there because the relationship between temps there and the "official" site were not known or at least documented. I am enclosing a pic of the two probes installed. When using the VDO probes on 2,3 on my old BMA EFIS, there was usually a 20F delta between front and back. The shroud should certainly help but it is very expensive. Homebrew anyone? Hi Paul, You are correct! The unipolar probes will not work at all. By design of the engine pod, the voltage across the temp sensitive resistor is not ground referenced and grounding the bottom of the resistor will screw the constant current injector driving the probe. Greg and I tried it anyway to see if it might work, but it was No Go. I would suspect that Westach probes will not work. Blue Mountain does not publish the sensor specs or cal curves but they use a UMA oem sensor element. If you are using a Gen4 unit, you as a user can not recalibrate to a different sensor. If you are using a previous generation EFIS, anything can be made to work but you will need to calibrate it. -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=175892#175892 Attachments: http://forums.matronics.com//files/chts_958.jpg

    Paul, The Rotax cht probes are grounded, one side, the housing is ground, and the other side is the connector. They are of the PTCor NTC type, that is a resistor, which changes it's resistance with temperature. Other types of probes are thermocouples, usually designated as "J" or "K" type probes, which produce a tiny voltage depending on the temperature of the junction. Those can be grounded or not. Whether you need resistive probes or "J" or "K" types probes is dependent on the EIS and it's inputs. My Dynon D180 accepts both, but only on certain positions.

    Jos It's using aircraft ground which a believe is the problem with the BMA EFIS - hence the need to use a thermistor with two wires. I believe the E1 uses it's own internal ground as reference so CHT and Oli temp need grounds going back to a ground pin on the EFIS. At the risk of upsetting Ira, and accepting I have very little expertise in the area, I wouldn't buy the Blue Mountain unit again. Not for a Rotax anyway and not flying in Europe. Still you live and learn.

    Jim, I just installed the Bob Archer Transponder ant. and, yes, it is supposed to go horizontally. The connector should be closest to the front of the aircraft with the opposite end (that containing the mass of the ant. copper element) should point towards the tail.

    Thanks Jim, I did drill those holes for pressure relief. I also added some extra plywood/fiberglass support around the triangle area at the wing root due to concerns of the skin flexing while people are entering or exiting the plane. I have quadruple checked for no tools or spare nuts & bolts and have cleaned, scuffed, and cleaned again the contact areas. Will epoxy today.

    Hi Ira, Because there is no factory data available for under spark plug temperatures, i did compare those with the original Rotax probes in head 1 and 3, and came to the 15 C higher outcome under normal loads. The spark plug sensors react much faster then the rotax probes, which can be expected, thermocouples have a much lower lag. The main reason for going this way however was to have an early warning available in case one of the barrels goes out of the normal. This, together with 4 EGT probes gives a pretty good picture on what's going on. I did go the expensive way, Rotax shroud. Which function is pretty much inhibited by the standard openings as i am experiencing now. I will come back and report on the next, closed eyes experiment. After all, this is an experimental!

    Let me know how it comes out Mike. I have quick-build flaps and after I got the skin on, noticed that one was a little long. I checked it and it was about 3/8 longer than it should have been so my day has been spent shortening it. I filled the outside ends of the flaps and ailerons. Are you doing a "pre" close before the final bonding? Bob Berube suggested that I do so and I'm glad I did.

    Paul, While i don't really want to be knit-picking, i don't quite understand why or where the engine ground would differ from internal ground. Unless there is a bad connection somewhere in between. However unlike thermocouples, there are many different characteristics for resistance probes. It may very well be that BMA thinks it's too much trouble to cope for Rotax probes in software. We'll certainly manage to upset Ira! Regards, Jos Okhuijsen Visit - www.EuropaOwners.org

    Jim, sorry, i first installed the antenna, then i read the manual and changed the polarization. Now i don't remember what's up and down :-) But i do remember a great sailing trip, and agree it's worth suffering an other border security check by those black uniformed #/#%/. But i am afraid it will take another year before it's possible, don't sell it yet! Regards, Jos Okhuijsen Visit - www.EuropaOwners.org

    Subject: Re: Spacer for Wing Top
    Mike- You mix the redux a little on the thick side using flox, then coat the ribs only. You then put strips of visqueen over them and install and weight the skin. In 24 hours you remove the weights, the skins, the plastic, scuff sand the redux, fill the voids, apply another tyhin coat of redux and re-apply the skins and weights. The reason for this is that some people have opened their wings for one reason or another and found there are voids between the ribs and skins. In my particular case, when we removed the skin after the pre-close, we found very few voids, so I would have been OK without it. I understand that the skins produced relatively recently fit much better than some of the earlier ones, so it may or may not be a step worth doing for you. My kit is A-283 and I don't know at what point they began doing a better job of fitting. Jim -------------- Original message -------------- From: DuaneFamly@aol.com Pre-close?
